Be it known that W6, FRANK E. HANNULA and WILLIAM E. TROMBLEY, citizens of the United States, residing-at Lansing, 1n the 5 county of Ingham and State of Michigan,

have invented a new and useful Improvement in Can Rubbers, of which the follow-' cover, it has been very difficult to remove the lid; The purpose of our invention is to ob-- viate this difficulty by so constructing therubber ring that, it shall be readily torn across and removed thus leaving the lid loose.

2 We attain this purpose by the means shown in the accompanying drawings 1n which 1gure 1 is a plan view of our mproved ring, the position of the reinforcing strip being indicated by dotted lines. Figure 2 1s a View of the edge of the ring, the reinforcing strip being there also indicated by dotted lines. In the drawings, 1 is the main 7 body of the ring, which is ofthe usual form, but is provided at some point of its circum- 3U ference with a projecting tongue, 2, that willproje'ct beyond the cover when the ring is in position and the cover applied, and thus furnishing a convenient hold for the fingers for tearing or removing the ring. A notch,

to prevent the tongue, 2, from tearing off 1922. Serial No. 562,552.

3, is made in the outer margin of the ring close to one side of the tongue, 2, to furnish a starting point for the tearing across of the ring. A reinforcing strip, at, of fibrous material is preferably imbedded in the tongue without breaking the ring.

'The operation of our device isas follows:

The person desiring to remove the top from the can takes hold of the tongue, 2, and pulls it. The rubber ring then tears across starting from the notch, 3. This breaks the ring and it is readily pulled out from under the cover.

We claim as our invention and desire to, secure by Letters Patent:

1. An article of the character described, comprising a ring formed of any'suitable material and provided on its outer margin with an integrally formed projection adapted to be grasped by the fingers, and a notch adapted to facilitate the rupture of said ring.

2. An article of the character described,

comprising a ring formed of any suitable material and provided on its outer margin with an integrally formed projection adapted to be grasped by the fingers, a notch adapted to facilitate the rupture of said ring, and a strengthening piece of suitable material imbedded in said projection and rin g FRANK E.
